ALLEN B. BROWN, OF PORTLAND, OREGON.

SASH-LOGK.

Application filed August 5, 191-1.

To aZZ whom it may concern Be it known that I, ALLEN B. BROWN, a citizenof the United States, residing at Portland, in the county of Multnomahand State of Oregon, have invented certain new and useful Improvementsin Sash-Locks, of which the following is a specification.

My invention relates to improvements in sash locks and refersparticularly to means for fastening screens or storm sashes, althoughthe invention might be used for other purposes and perform its functionsin a proper manner.

One of the objects of the invention is the provision of a sash lockwhich will permit of the instant application of the sash and which willpositively retain the sash and which can be readily attached or removedwhen found necessary and desirable.

With these objects in view my invention consists of a sash lock of thecharacter stated and for the purpose intended embodying novel featuresof construction and combination of parts substantially as disclosedherein.

In order that the construction in detail and the operation of myinvention may be fully understood and its many advantages beappreciated, 1 have shown in the accompanying drawings a sash lockembodying my invention.

Figure 1 is a perspective view of the complete lock. Fig. 2 represents afront elevation of the lock casing. Fig. 3 represents a perspective viewof the casing plate and lock casing, the two members constituting myinvention. Fig. 4 represents a perspective view of the cover plate ofthe casing. Fig. 5 represents a perspective View of the casing showingthe means for retaining the pivoted lock of my device. Figs. 6 and 7represent perspective views of the pivoted locking plate shown inunlocked and locked positions, respectively, and Fig. 8 represents aperspective View of a modified form of my device employing a rectangularcasing.

Referring by numeral to the drawings in which similar characters ofreference denote corresponding parts in all of the views The numeral 1designates the window casing, and 2 designates the frame of the storm orscreen sash and to the casing 1 is secured the stationary attachingplate 3, which is formed with the locking lug 4, and to the sash casing2, is secured the casing 5, which is of semi-circular shape in crosssection Specification of Letters Patent.

and its front vertical wall 6, is provided with a slot or passage 7,which leads to the entering opening of enlarged size 8, formed in thecap plate or cover 9. From this construction it will be observed thatthe attaching plate is secured to the window frame or casing 1, and isprovided with a lug or head 1, which is adapted to enter the opening 8of the cap plate 9, and to seat in the slot 7, in the wall 6 of saidcasing, and in said casing is secured the yokeshaped spring 10, whichhas its free arm 11 arranged in rear of said slot 7, and exerting itstension upward and provided with a locking pin 12, this spring isconfined in the casing by means of the plate 13, said plate being formedwith a cavity or recess 14L, in its body portion, which leads at oneside to the channel 15, and at its other side to the opening 17, whichis in line with the slot 7 and the enlarged opening 8, of the cap plate9. From this construction it will be observed that the plate 13 fitswithin the casing 5, and that the locking pin 12, of the casing 5extends upward through an opening 18 in said plate 13, and from Figs. 6and 7 it will be noticed that the locking plate 19, is pivoted at 20, inthe cavity of said plate and its inner end, when in unlocked position asshown in Fig. 6, retained free of the opening 17 thereof, by means ofsaid locking pin 12, with its finger portion 19, extending out throughthe channel 15, said locking plate being controlled by the fiat spring21, which has one end engaging the plate at 22, and its other endengaging the finger portion of said locking lever or plate at 23.

In the form of my invention shown in Fig. 8, the construction ispractically identical, except that I employ a rectangular casing 24 withcover plate 25, and use an angular shaped entrance opening 26, theoperation being identical with the other form of my invention.

From the foregoing description taken in connection with the drawings,the operation of my invention will be readily understood and it will benoted that, when the parts are in normal position the locking leverplate is in the position shown in Fig. 6, and upon bringing the lug uponthe attaching plate into the entrance opening, said lug engages thespring arm 11, which engagement releases the locking pin 12 allowing thespring 21 to move the locking lever plate to the position shown in Fig.7, confining lug 4: be-

to release the latch it is simply necessary to v move the pivoted leverplate by pressure of the thumb to one side when after the sash isremoved it will be retained by the locking pin 12.

I have shown only one of the devices, but it will be understood that inuse a number are employed fastened at suitable places to the windowcasing and sash, and it will be understood that I provide a device whichwill permit of the instant application or removal of the sash, whichretains the sash in position under all conditions, which is ofattractive appearance and simple, durable and inexpensive, thusembodying the features to insure a practical and eificient improvementof this character.

I claim 1 In combination with the casing and sash,

a platesecured to the casing and provided with a lug, a casing securedto the sash and having an opening to receive said lug, and means mountedin the casing for confining said lug within said casing, said meansconsisting of a spring. arranged adjacent the lug receiving opening ofthe casing having a locking pin, a plate mounted in said cas- ALLEN B.BROWN.
